摘要:
太湖流域浙江片区受工业和城市废水以及农田地表径流等人为因素的影响,污染问题日益严重,根据2013年的水文巡测以及水质监测资料,分析了太湖流域浙江片区出入境水量和高锰酸盐指数(CODMn)、氨氮(NH3-N)、总氮(TN)和总磷(TP)等水质指标的出入境通量及其时空分布.结果表明,2013年太湖流域浙江片区出入境水量以出境为主,出入境断面的首要污染物是TN,其平均浓度在各出入境断面均处于Ⅴ~劣Ⅴ类水平,CODMn、NH3-N和TP的平均浓度总体上达到Ⅱ~Ⅲ类标准.4种污染物的出入境通量均以出境为主,研究区域北部是污染物的主要入境断面,东部是污染物的主要出境断面.净出境水量是影响污染物净出境通量的关键因子,出入境断面水质是净出境通量的主要影响因子.源头控制农业面源污染、将工业废水和城镇生活污水处理达标后排放是减轻太湖流域浙江片区水体污染的关键,是太湖流域水体污染控制和治理的主要措施.

Abstract:
Zhejiang area of Taihu Basin is affected by human factors such as industrial, urban wastewater and farmland surface runoff. Pollution problems are becoming more and more serious. Based on the data of hydrological survey and water quality monitoring in 2013, inbound and outbound water quantity and spatial-temporal distribution of water quality indexes such as permanganate index (CODMn), ammonia nitrogen (NH3-N), total nitrogen (TN) and total phosphorus (TP) in Zhejiang area of Taihu Basin were analyzed. The results showed that the inbound and outbound water quantity in Zhejiang area of Taihu Basin in 2013 was mainly outbound. The primary pollutant in the entry-exit section is TN. The average concentration is in the V-inferior V level in all entry-exit sections. The average concentrations of CODMn, NH3-N, and TP generally reach the Ⅱ-Ⅲ standard. The outbound and inbound fluxes of the four pollutants are mainly outbound. The northern part of the study area is the main inbound section of pollutants, and the eastern part is the main outbound section of pollutants. The net outbound water quantity is the key factor affecting the net outbound flux of pollutants, and the water quality of the entry-exit section is the main factor affecting the net outbound flux. The key to reducing water pollution in Zhejiang area of Taihu Basin is controlling agricultural non-point source pollution and discharging industrial wastewater and urban domestic sewage after reaching the standard, which is the main measure of water pollution control and treatment in Taihu Basin.
Key words:  Taihu Basin  water quantity  water quality  pollutant flux  correlation analysis
